I scoffed at first, but I guess the qualification is about water safety and things, just in case?

I know what you mean - I also had a bit of a similar reaction at first - but as I understand it's how to run lessons on a beach without classroom teaching materials to hand, how to use things on the beach in the context of certain subjects etc. Also, I said "qualification" which probably makes it sound grander than it is - she just went on a 3 or 4 day course.

You should've stopped at the scoff. Someone qualified to handle children in a classroom and in field trips is already qualified to take them to a beach.

I think you may be misunderstanding, which is perhaps understandable given that I didn't unpack what it meant - see my sibling comment. But scoffing without asking for more information isn't a great strategy for learning.

I grew up in a beach town and gone to the beach in kindergarten all the time with the school without any special certifications. In the event kids go into the water there's always a lifeguard on duty already so otherwise it's the same as any other school outing, I'm not sure what the difference would be from leading a group of children in a city walk for example which to me looks way more dangerous.

Making kids go to the beach in the rain isn't a great strategy either.

Rain is a good thing
